Snowflakes and Névé

    Cards (6)

    • What do snowflakes do to air?
      They trap air
    • How is Névé created?
      Snow settles on top of each other and compresses to eventually become firm and compact
    • Where is Névé more likely to build up?
      In North facing ledges or hollows as they receive the least sun
    • What happens to Névé in the Alps?
      Meltwater percolates into the névé and freezes, causing an increasingly dense mass
    • How is true ice formed?
      Air is progressively squeezed out of the névé, and eventually after 20-40 years, it will have turned into true ice
    • What is Pressure Melting Point?
      Small increases of pressure can cause ice to melt, therefore as you go further down in a glacier, ice is more likely to melt due to the pressure of the weight of ice on top of it
